Question
A six-face fair dice is rolled a large number of times. The mean value of the outcomes is ________
Concept:
Mean = \(\sum\limits_x {x.{f_x}} \)
Calculation:
Value on the die (x) | 1 | 2 | 3 | 4 | 5 | 6 |
Probability P(X) | 1/6 | 1/6 | 1/6 | 1/6 | 1/6 | 1/6 |
Mean = \(\sum\limits_x {x.{f_x}} \)
= 1.(1/6) + 2.(1/6) + 3.(1/6) + 4.(1/6) + 5.(1/6) + 6.(1/6)
= 3.5
